Rin was lying beneath him, waiting, watching with wide, round eyes full of expectation. She was keen to start, but for Kyousuke, it took a bit of mental preparation before he could actually commit the act for the first time. He swallowed thickly and reached out to touch her face, stroking a thumb over her cheek.
The only sound to be heard was Rin's faint breathing. She blinked, a flicker of concern passing over her face. "Hey... are you okay?"
Did he look that nervous? Kyousuke shook his head and smiled. "Sorry. I was just thinking."
"Alright."
His little sister. His sibling.
Kyousuke moved his hand down, resting it upon her chest. He felt her pulse beating beneath her warm skin.
They had been together their whole lives, side by side, brother and sister, always walking together and now here they were, fully prepared to commit a sin. Their status as siblings was going to be forever altered.
This wasn't a decision you just made on the fly. There was so much to think about. Would they be able to hide this for the rest of their lives or would the day come when they had to tell everyone? What if they fell out and broke up? A flurry of thoughts tumbled through his mind, one after another.
"Kyousuke?" Rin's brow furrowed.
And he'd gone and got lost in his thoughts again. They were never going to get started at this rate. Kyousuke leaned in to kiss her. This really wasn't the easiest thing in the world. To be honest, part of him wanted to stop this in its tracks, to turn back before it was too late, but at the same time, another part of him wanted to sample the forbidden fruit, to take this daring leap with her and make a new start in their relationship.
Temptation won over reason, and he leaped.
